  Log:
  Fixed diskcache key storage shutdown bug.  Added debugging
information.
  
  I think there is a problem if stuff is being written to disk during
the final stage of the optimization.  This should be easy to fix.
  
  I also need to make sure that the maxlife parameter is getting stored
properly.

               src/java/org/apache/jcs/auxiliary/disk/indexed
                        IndexedDiskCache.java

                        AbstractDiskCache.java
  Log:
  It should be safe to dispose now.  Kill queue, optimize, then play
dead.
  
  Fixed a problem in the ReadWriteLock class that let the number of
writelocks get below zero.  This seems to have solved many problems.
However, I can't find out why there are more done calls than lock calls.
Added a break into the wait on the readlock in case noone calls notify.
  
  This may have fixed the mysterious locking problem that I've never
been able to duplicate.
